Display Control Device and Non-Transitory Computer Readable Medium Storing Display Control Program for Setting Display Time According to Display Priority

1. A display control device comprising: an image sensor that acquires an image; a storage device that stores a plurality of mages acquired by the image sensor; and a central processing unit (CPU) that controls each image stored in the storage device to be displayed sequentially on a display device during a fixed time, and performs control of changing a time for which each of an acquired new image and the plurality of images stored in the storage device is displayed on the display device according to a display priority of each image in a case where the image sensor acquires the image.

2. The display control device according to claim 1 , wherein the central processing unit (CPU) performs control such that an image having a high priority is displayed on the display device for a time which is not shorter than an average display time after a new image is acquired in a case where the image sensor acquires the image.

3. The display control device according to claim 2 , wherein the central processing unit (CPU) performs control such that the image having a high priority is displayed on the display device for a time which is not shorter than a display time before the new image is acquired.

4. The display control device according to claim 1 , wherein the central processing unit (CPU) performs control such that an image having a low priority is displayed on the display device for a time which is not longer than an average display time after a new image is acquired.

5. The display control device according to claim 4 , wherein the control of a display time in the display device, performed by the central processing unit (CPU), includes control of not displaying an image.

6. The display control device according to claim 1 , wherein, in a case where the number of images stored in the storage device is equal to or larger than a predefined number, the central processing unit (CPU) performs control of changing a time for which each of an acquired new image and the plurality of images stored in the storage device is displayed on the display device according to a display priority of each image.

7. The display control device according to claim 6 , wherein the central processing unit (CPU) performs control of reducing a display time by the number of images exceeding the predefined number according to the display priority of each image.

8. The display control device according to claim 7 , wherein the central processing unit (CPU) performs control such that images of the number exceeding the predefined number are not displayed according to the display priority of each image.

9. The display control device according to claim 1 , wherein, in a case where the image sensor acquires an image, the central processing unit (CPU) displays the acquired new image and the plurality of images stored in the storage device in separate display regions according to a display priority of each image.

10. The display control device according to claim 9 , wherein the central processing unit (CPU) determines a size of a region in which an image is displayed according to the display priority of each image.

11. The display control device according to claim 9 , wherein the central processing unit (CPU) controls the number of separate regions displayed in a display region according to the display priority of each image.

12. A non-transitory computer readable medium storing a display control program causing a computer to function as: an image sensor that acquires an image; a storage device that stores a plurality of images acquired by the image sensor; and a central processing unit (CPU) that controls each image stored in the storage device to be displayed sequentially on a display device during a fixed time, and performs control of changing a time for which each of an acquired new image and the plurality of images stored in the storage device is displayed on the display device according to a display priority of each image in a case where the image sensor acquires the image.

13. A display control device comprising: acquisition means for acquiring an image; storage means for storing a plurality of images acquired by the image sensor; and display control means for controlling each image stored in the storage device to be displayed sequentially on a display device during a fixed time, and performing control of changing a time for which each of an acquired new image and the plurality of images stored in the storage device is displayed on the display device according to a display priority of each image in a case where the image sensor acquires the image.
